The answer to 9h + 2 < -79 is H < -9
9h+2<-79 yea that's the question but what's the answer?
h=16
-9h-6+12h+40=22 -9h+12h=22-40+6 3h=-12 h=-4
9h + 2 < - 79 subtract 2 to both sides 9h < - 81 divide by 9 to both sides h < -9 All numbers less than 9 are solutions for the inequality. Note that 9 is not a solution.
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
-9h-6+12h+40=22
-9h - 6 + 12h + 40 = 22, simplifying this gives12h - 9h + 40 - 6 = 223h + 34 = 22, taking 34 off both sides gives3h + 34 - 34 = 22 - 343h = -12, thush = -12/3 = -4
There are two terms in that expression. They are " 9h " and " 13 ".
9h^2+24h+16=(9h+16)(h+1)
